Creating a Bank of Batteries
1 Comment20 October 2022 | Paul
Today we are going to look at the basic rules to follow when creating a leisure battery bank. Creating a bank of batteries is a great way to increase the amount of energy that your batteries can store and produce. There are 2 ways a battery bank can be wired up, either in series or parallel but for this article, we won't be looking into these too much so for more information check out our knowledge centre article here. Instead, we are going to look at the often overlooked items to note when wiring 2 batteries together.
Rule 1: Batteries should match each other
The first rule of creating a battery bank is to make sure your batteries match. This is not just a case of adding a similar battery, it would need to be of the same type and capacity (ideally the same brand and model) as the 1st battery in the bank. This is because both batteries need to stay balanced to perform at their best and by mixing and matching you can cause serious imbalance and performance drops.
Rule 2: Use batteries that are the same age
Imbalance in the battery bank can also be affected by age as over time, a battery's ability to store energy drops. As a result, an older battery may not be charging at the same rate as a newer battery which would cause an imbalance.
Rule 3: Cable sizing
Buying cable to connect batteries can cause some confusion but thankfully it can be made a little easier. To help make sure your appliances can draw power evenly from all the batteries in the bank, you will want to make sure that all interconnecting cables are the same length and gauge. This simple rule of thumb means all the batteries will be evenly used to power your equipment.
